Aplumber changes 40 dollars to come to the house and 30 dollars for each hour spent working on your plumbing . if x represents the number of hours of work and y represent total charge the plumber makes, write the equivalent in part a. c if the plumber work 5 hours how much was the total charge? if the charge was 115 dollar how hours did the plumber spent working

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
